#ifndef __STL_CONFIG_H
# define __STL_CONFIG_H

// Flags:
// * __STL_NO_BOOL: defined if the compiler doesn't have bool as a builtin
//   type.
// * __STL_HAS_WCHAR_T: defined if the compier has wchar_t as a builtin type.
// * __STL_NO_DRAND48: defined if the compiler doesn't have the drand48 
//   function.
// * __STL_STATIC_TEMPLATE_MEMBER_BUG: defined if the compiler can't handle
//   static members of template classes.
// * __STL_STATIC_CONST_INIT_BUG: defined if the compiler can't handle a
//   constant-initializer in the declaration of a static const data member
//   of integer type.  (See section 9.4.2, paragraph 4, of the C++ standard.)
// * __STL_CLASS_PARTIAL_SPECIALIZATION: defined if the compiler supports
//   partial specialization of template classes.
// * __STL_PARTIAL_SPECIALIZATION_SYNTAX: defined if the compiler 
//   supports partial specialization syntax for full specialization of
//   class templates.  (Even if it doesn't actually support partial 
//   specialization itself.)
// * __STL_FUNCTION_TMPL_PARTIAL_ORDER: defined if the compiler supports
//   partial ordering of function templates.  (a.k.a partial specialization
//   of function templates.)
// * __STL_MEMBER_TEMPLATES: defined if the compiler supports template
//   member functions of classes.
// * __STL_MEMBER_TEMPLATE_CLASSES: defined if the compiler supports 
//   nested classes that are member templates of other classes.
// * __STL_EXPLICIT_FUNCTION_TMPL_ARGS: defined if the compiler 
//   supports calling a function template by providing its template
//   arguments explicitly.
// * __STL_LIMITED_DEFAULT_TEMPLATES: defined if the compiler is unable
//   to handle default template parameters that depend on previous template
//   parameters.
// * __STL_NON_TYPE_TMPL_PARAM_BUG: defined if the compiler has trouble with
//   function template argument deduction for non-type template parameters.
// * __SGI_STL_NO_ARROW_OPERATOR: defined if the compiler is unable
//   to support the -> operator for iterators.
// * __STL_DEFAULT_CONSTRUCTOR_BUG: defined if T() does not work properly
//   when T is a builtin type.
// * __STL_USE_EXCEPTIONS: defined if the compiler (in the current compilation
//   mode) supports exceptions.
// * __STL_USE_NAMESPACES: defined if the compiler has the necessary
//   support for namespaces.
// * __STL_NO_EXCEPTION_HEADER: defined if the compiler does not have a
//   standard-conforming header <exception>.
// * __STL_NO_BAD_ALLOC: defined if the compiler does not have a <new>
//   header, or if <new> does not contain a bad_alloc class.  If a bad_alloc
//   class exists, it is assumed to be in namespace std.
// * __STL_SGI_THREADS: defined if this is being compiled for an SGI IRIX
//   system in multithreaded mode, using native SGI threads instead of 
//   pthreads.
// * __STL_WIN32THREADS: defined if this is being compiled on a WIN32
//   compiler in multithreaded mode.
// * __STL_PTHREADS: defined if we should use portable pthreads
//   synchronization.
// * __STL_UITHREADS: defined if we should use UI / solaris / UnixWare threads
//   synchronization.  UIthreads are similar to pthreads, but are based 
//   on an earlier version of the Posix threads standard.
// * __STL_LONG_LONG if the compiler has long long and unsigned long long
//   types.  (They're not in the C++ standard, but they are expected to be 
//   included in the forthcoming C9X standard.)
// * __STL_THREADS is defined if thread safety is needed.
// * __STL_VOLATILE is deifined to be "volatile" if threads are being
//   used, and the empty string otherwise.


// User-settable macros that control compilation:
// * __STL_USE_SGI_ALLOCATORS: if defined, then the STL will use older
//   SGI-style allocators, instead of standard-conforming allocators,
//   even if the compiler supports all of the language features needed
//   for standard-conforming allocators.
// * __STL_NO_NAMESPACES: if defined, don't put the library in namespace
//   std, even if the compiler supports namespaces.
// * __STL_NO_RELOPS_NAMESPACE: if defined, don't put the relational
//   operator templates (>, <=. >=, !=) in namespace std::rel_ops, even
//   if the compiler supports namespaces and partial ordering of
//   function templates.
// * __STL_ASSERTIONS: if defined, then enable runtime checking through the
//   __stl_assert macro.
// * _PTHREADS: if defined, use Posix threads for multithreading support.
// * _UITHREADS:if defined, use SCO/Solaris/UI threads for multithreading 
//   support
// * _NOTHREADS: if defined, don't use any multithreading support.  
// * __STL_USE_NEW_IOSTREAMS: if defined, then the STL will use new,
//   standard-conforming iostreams (e.g. the <iosfwd> header).  If not
//   defined, the STL will use old cfront-style iostreams (e.g. the
//   <iostream.h> header).

// Other macros defined by this file:

// * bool, true, and false, if __STL_NO_BOOL is defined.
// * typename, as a null macro if it's not already a keyword.
// * explicit, as a null macro if it's not already a keyword.
// * namespace-related macros (__STD, __STL_BEGIN_NAMESPACE, etc.)
// * exception-related macros (__STL_TRY, __STL_UNWIND, etc.)
// * __stl_assert, either as a test or as a null macro, depending on
//   whether or not __STL_ASSERTIONS is defined.


//  本配置文件功能表:  
//  (1)  如果不编译器没有定义bool, true, false则定义  
//  (2)  如果编译器不支持drand48()函数则定义__STL_NO_DRAND48  
//       注: drand48产生双精度的伪随机数, 因为采用了48bit计算, 故名drand48  
//  (3)  如果编译器不支持static members of template classes(模板类静态成员),  
//       则定义__STL_STATIC_TEMPLATE_MEMBER_BUG  
//  (4)  如果编译器不支持'typename'关键字, 则将'typename'定义为空(null macro)  
//  (5)  如果编译器支持partial specialization of class templates(模板类偏特化),  
//       则定义__STL_CLASS_PARTIAL_SPECIALIZATION  
//       参考文献: http://msdn.microsoft.com/en-us/library/9w7t3kf1(v=VS.71).aspx  
//  (6)  如果编译器支持partial ordering of function templates(模板函数特化优先级),  
//       则定义__STL_FUNCTION_TMPL_PARTIAL_ORDER  
//       参考资料: http://msdn.microsoft.com/zh-cn/library/zaycz069.aspx  
//  (7)  如果编译器支持calling a function template by providing its template  
//       arguments explicitly(显式指定调用模板函数的模板参数)  
//       则定义__STL_EXPLICIT_FUNCTION_TMPL_ARGS  
//  (8)  如果编译器支持template members of classes(类模板成员),  
//       则定义__STL_MEMBER_TEMPLATES  
//  (9)  如果编译器不支持'explicit'关键字, 则将'explicit'定义为空(null macro)  
//  (10) 如果编译器不能根据前一个模板参数设定后面的默认模板参数,  
//       则定义__STL_LIMITED_DEFAULT_TEMPLATES  
//  (11) 如果编译器处理模板函数的non-type模板参数类型推断有困难,  
//       则定义__STL_NON_TYPE_TMPL_PARAM_BUG  
//  (12) 如果编译器不支持迭代器使用'->'操作符,  
//       则定义__SGI_STL_NO_ARROW_OPERATOR  
//  (13) 如果编译器(在当前编译模式下)支持异常,  
//       则定义__STL_USE_EXCEPTIONS  
//  (14) 如果我们将STL放进命名空间中,  
//       则定义__STL_USE_NAMESPACES  
//  (15) 如果本STL在SGI的编译器上编译, 并且用户没有选择pthreads或者no threads,  
//       则默认使用__STL_SGI_THREADS  
//       注: POSIX thread 简称为pthread, Posix线程是一个POSIX标准线程.  
//  (16) 如果本STL在Win32平台的编译器上使用多线程模式编译,  
//       则定义__STL_WIN32THREADS  
//  (17) 适当的定义命名空间相关的宏(__STD, __STL_BEGIN_NAMESPACE, 等)  
//  (18) 适当的定义异常相关的宏(__STL_TRY, __STL_UNWIND, 等)  
//  (19) 根据是否定义__STL_ASSERTIONS, 将__stl_assert定义为断言或者空(null macro)
